y To a/ZZ whom, it may concern/.-

Be it known that I, CARL WILHELM SDER- BERG, a citizen of Norway, andaresidentof Nordstrand, near Christiania, Norway, have invented certainnew and useful Improve? ments in Apparatus for GeneratingAcetylene Gas,of which the following is a specification.

My invention relates to apparatus for generating acetylene gas, and moreespecially to that class of such generators in which certainquantitiesof calcium carbid are from time to time bymechanical meansthrown into a body of water contained in a icloscd vessel communicatingwithan expansible gas-reservoir.

The object of my invention is to provide an improved apparatus of thiskind which is simple in'fconstruction and operation and which is soconstructed and arranged that no air can possibly enter the generator'when the apparatus is charged with new carbid and so no gas can escapeduring charging operation.

It is also the object of my invention to so construct the apparatus thatthe moving'or.

operating parts of the same are out of cont-act with the gas, wherebythey are prevented from becoming corroded by the action of the gas andwhereby easy access to the saidparts may be had. l

My invention consists in thev combination,

' with a container for water having a number of carbid-receptaclesplaced on its top, of movable covers closing said receptacles tothe'interior of the water-container andof vmeans for automaticallyopening and closing said covers through the action of the verticalmovement of the expansible gas-reservoir;`

and it also consists in certain special features of arrangement andconstruction whereby the aforesaid objects are attained.

In order to fully explain'my'invention, I have shown in the accompanyingdrawings an apparatus constructed in accordance with my invention; butit is tobe understood that the apparatus shown` is only one of the formswhich the same'may be given.

In the drawings, Figure l represents a side elevation, partly insection, of the said improved apparatus. Fig. 2 is a horizontal plan ofthe same. Fig. 3 is a detail view of one of the carbid-containers. Figs.i and 5' are rea and the gasometer h. The gas-generator a consistsof thewaterreservoir,`which is funnel-shaped below, as shown at et', and isprovidedwith the discharge-pipe g,'said resvervoirbeing filled withwater to`about three- "fourths/'ot' itsheight and closed above ingasproof In'anner by a top a2 and wall a3, depending into thewater,-for1ning a water seal. From this wall extends inwardly anddownwardly a deiiecting-wall a4, the lower edges of -thiswalland thewall a3 contacting with the supplemental perforated bottom a5. By meansof atube o running-into the upper partqof the generator the acetylenegas collecting over the water is fed to the gasometer b. This maybeofthe ordinary or any desired construction and comprises a body h andmovable bell h', the latter being guided by antifriction-rollersbbearingfagainst vertical posts-or rods 198. -0nthe'upper part' of thegas-generator a number offreservoirs A are arranged. Nine of these areshown in the drawings for purposes of illustration. They serve asrecipientsforv the carbid. These receptacles are locked'- in gas-proofmanner above by a lidor cover A', secured in place ,bya suitable clampA2, while a lid B, which lcan be opened, is closely pressed against thelunder side.' Under each carbid-receptacle A, vwhich is reduced somewhatvtoward the upper part for the purpose of betterrelease of the carbid, acylinder Lis sitnated'which reaches through the top a2 ofthe generatorvessel ct and extends somewhat below the level of the water. The lids orcovers B, which close the lower ends of the carbid-reservoirs,

have each on their axle or shaft C, on which they rock, a weighted leverD, which rests with its lower edge d on a disk G, which is pivoted on apin F on the top a2 of the generatorcasing a. This dish or plate Gr isIOO when the bell b' sinks. In this action the edges d rub on the diskG, so that the lids B of the carbid-reservoirs are constantly keptlocked by the revolving disk G. This disk G is provided with an openingIFI,which when it reaches a position under the lever D of al cover Ballows the lid B to open, as the disk D and the weight of the lid Bcauses it to fall, thus opening the carbid-reservoir. The contents ofthe carbid-reservoir A fall into the water vessel a. It is apparent fromthe above that with every descent of the bell b a carbid-receptacle A isopened and the contents thereof discharged into the water-reservoir a.The contents of a carbid-receptacle A will develop an amount of gasequal to the quantity required to fill the gasometer. The revolution ofthe disk or plate G occurs only at the descent of the receiver or bellb', while it stands still when the same ascends upon introduction ofcarbid in the water. This action of the mechanism is d'ue to the mannerin which one of the toothed wheels N or O is mounted on its axle, one ofkthese wheels being not keyed to the axle, but is loose on the same,being provided with a spring-pawl cooperating with a ratchet-wheel onthe axle, so that the toothed wheel may move freely in one directionwithout taking the axle with it, while in the other direction it movestogether with the axle.

In order to ascertain from the outside which receptacles A are stillfilled with carbid and which are empty, a little indicator K is arrangedon each carbid-receptacle A, which indicator is turnedl by an arm I,connected with the disk G at the point where the carbid-receptaclesdischarge. In order to permit the downward movement of the bell withouta corresponding backward movement of disk G, gear-wheel O is looselyTmounted on shaft O/ and carries a pawl o, pressed by a spring 0' intoengagement with a ratchet-Wheel 02 on the shaft O. A gravity-pawl g,engaging circularly-arranged ratchet-teeth g on the under side of thedisk G, prevents any backward movement thereof. If this indicator Kstands vertical, the reservoir is filled if hori` zontal the reservoiris empty. In manipu lating the apparatus it is only necessary td feedthe emptied carbid-reservoirs at determined intervals again with carbid.

The advantages which distinguish the acetylenegas generator describedabove over others with automatic action consist,primarily,in thestationary arrangement of the individual carbid-chambers, so that theyneed not move in the operation of the apparatus. Furthermore, anotheradvantage is obtained for the presentapparatus because the various partseffecting the automatic feed of carbid are arranged outside of thegas-room. These mechanisms are, therefore, not exposed to the humidityand the highly destructive influence of the sulfureted hydrogen, thephosphureted hydrogen, and the ammonias, rbc., developing in thegeneration of the acetylene. The particular construction of` theregulating mechanism renders the whole apparatus rather insensibleagainst shocks and similar inuences. Furthermore, carbid cannot underany circumstances be introduced into the water at an improper time. Thisfeed of carL bid is regulated by the operation of the apparatus in themost positive manner. over, this apparatus permits no air to penetrateinto the generator when the carbid-rea ceptacles are being filled.

I claim- In an acetylene-gas generator in combina= tion, agenerator-chamber, a fixed top or cover for the same, a circular row ofxed tubes passing through the said fixed top and dipping into the Waterof the generator-chamber, carbid-receptacles of less diameter than thesaid fixed tubes mounted'on top ofsuch tubes and provided with air-tightcovers at the top, throttle-valves mounted within said tubes and formingmovable bottoms for the said receptacles, operating-shafts for holdingthe said bottoms up against the shoulders formed between the tubes andthe receptacles, said operating-shafts having their operative endsplaced outside the generator-chamber and means for operating the shaftssubstantially as described.

In witness whereof I have hereunto set my hand in presence of twoWitnesses.
